Combine mass properties and uncertainties

combine_mass_props_and_unc() is a convenience wrapper that concatenates the results of combine_mass_props() and combine_mass_props_unc().

Usage

combine_mass_props_and_unc(mpl)

Arguments

mpl

A list of mass properties and uncertainties lists, each of which contains the following named elements:

• mass Numeric mass.

• center_mass Numeric 3-vector center of mass.

• point Logical indicating point mass. The inertia of point masses is excluded from calculations.

• inertia Numeric 3x3 matrix inertia tensor.

• sigma_mass mass uncertainty

• sigma_center_mass center of mass uncertainty (3-dimensional numeric)

• sigma_inertia Inertia tensor uncertainty (3x3 numeric matrix)

Value

Combined mass properties list with the same named elements.

Examples

leaves <- names(igraph::neighbors(sawe_tree, "Combined", mode = "in"))
mpl <- Map(f = function(id) get_mass_props_and_unc(sawe_table, id), leaves)
